To optimize the display of images in your application or in your site, you have the ability to use HFSQL thumbnails.

A HFSQL thumbnail corresponds to an image automatically generated from an image stored in a HFSQL binary memo. One or more thumbnails of different sizes can be generated for each HFSQL binary memo item.

For example, the "ProductImage" item allows you to generate two HFSQL thumbnails:

a small thumbnail used in a Looper control,

a larger thumbnail used in the product forms.

The thumbnail that best suits the control used to display the image will be automatically selected by the HFSQL engine.

Remarks:

We advise you to display the thumbnails in a Thumbnail control (and not in an Image control).

The thumbnails are not available when accessing a database via Remote access.

To use the HFSQL thumbnails in Linux, the libfreetype6 library (libfreetype.so.6) must be installed on the current computer.
